Grease Chair

The chair a man sits in while masturbating to internet porn. Easily identified by the semen stains on the chair.

Mike: What's the deal with this chair Chuck? You spill a bunch of toothpaste on it?

Chuck: No, that's my grease chair. Bangbros just got some new vids up and I had a good tossing session.

Mike: Nice! That explains the tissues all over.
